INTRODUCTION 

THE  Works  of  the  South wark  Foundry  and  Machine 
Company  were  founded  in  1836,  and  occupy  the  entire 
block  bounded  by  Washington  Avenue,  Federal  Street, 
Fourth  and  Fifth  Streets,  covering  about  five  acres  of  ground, 
in  the  southern  section  of  Philadelphia,  known  in  the  early 
history  of  the  city  as  the   District  of   "  South wark,"   from 
which  our  name  is  derived. 

The  Works  consist  of  Machine  and  Erecting  Shops, 
Boiler  Shop,  Smith  Shop,  Iron  and  Brass  Foundries,  Pattern 
Shop  and  Pattern  Store  Houses. 

The  Machine  Shops  have  an  aggregate  floor  space  of 
65,500  square  feet,  and  contain  a  complete  equipment  of 
modern  tools  and  special  appliances  for  finishing  the  largest 
castings  and  forgiugs  used  in  engineering  construction. 

The   Main   Erecting   Shop,    which   is    76  feet  wide  by

Introduction 

253  feet  long,  is  equipped  with  two  electric  traveling  cranes, 
each  capable  of  handling  fifty  tons. 

The  Iron  Foundries  cover  an  area  of  40,250  square  feet, 
and  are  equipped  with  three  traveling  cranes  of  fifteen,  thirty 
and  fifty  tons  capacity  respectively.  Our  facilities  for  making 
castings  of  all  kinds  are  unexcelled.  Modern  melting  fur- 
naces, core  ovens  and  core  sheds,  together  with  the  crane 
facilities  before  mentioned,  and  improved  methods  of  hand- 
ling the  raw  materials,  enable  us  to  produce  iron  castings  at 
the  cheapest  possible  cost  and  of  the  largest  sizes  practicable. 

In  our  Brass  Foundry  we  have  facilities  for  the  produc- 
tion of  bronze  and  composition  Castings  of  any  description. 

The  Boiler  Shop,  107  feet  wide  by  190  feet  long,  is 
fitted  out  with  hydraulic  riveting  machinery  and  all  modern 
appliances  for  building  boilers  of  large  size.  We  make  a  spe- 
cialty of  Horizontal  Tubular  Boilers,  Marine  Boilers  for  high 
pressures,  Tanks,  Stacks,  and  Miscellaneous  sheet  iron  work. 

The  Pattern  and  Smith  Shops  are  fitted  with  modern 
appliances  for  rapidly  turning  out  work  in  their  line. 

Hence  it  will  be  seen   that   we  control  practically  all

Introduction 

branches  of  the  business  pertaining  to  the  manufacture  of 
the  various  classes  of  machinery  we  build. 

The  tracks  of  the  Pennsylvania  Railroad  Company  are 
located  on  Washington  Avenue,  and  three  sidings  enter  the 
Works,  which  enables  us  to  receive  all  supplies  by  carload  and 
ship  our  products  in  the  same  manner.  This  railroad  con- 
nects with  all  the  Trunk  lines  of  the  country,  facilitating 
transportation  to  any  point  at  lowest  rates. 


PORTER-ALLEN  ENGINES 

ONE  of  our  leading  specialties  is  the  manufacture  of  the 
Porter-Allen  Automatic  Engine,  in  sizes  of  45  H.  P. 
and  upwards.     The  smaller  engines  up  to  150  H.  P. 
are  built  exclusively  of  the  simple  high  pressure  type  ;  above 
150  H.  P.  we  build  them  both  Simple,  Compound  and  Triple 
Expansion,  to  meet  the  requirements  of  the  purchaser. 

We  publish  a  treatise  of  this  engine  which  gives  an 
exhaustive  description  of  the  design  and  construction,  and 
are  pleased  at  all  times  to  furnish  interested  parties  with  a 
copy  of  the  same. 

In  general,  the  advantages  of  this  engine  are  its  high 
economy  in  the  use  of  steam  ;  close  regulation  under  widely 

6 


Porter- Allen  Engines 

fluctuating  loads ;    convenience  and  economy  of  installation 
and  adaptability  of  service. 

In  connection  with  the  foregoing  notice  of  special  ad- 
vantages, and  which  we  might  largely  extend,  we  will  but 
briefly  invite  attention  to  the  general  character  of  the  work 
put  upon  these  engines. 

This  is  intended  to  be  such  as  to  render  them  free  from 
the  ordinary  troubles  which  are  met  with  in  the  care  of 
steam  engines,  and  to  give  them  a  durability  that  shall  leave 
nothing  to  be  desired.  To  accomplish  this,  no  pains  have 
been  or  will  be  spared. 

In  addition  to  a  self-contained  and  substantial  construc- 
tion, which  maintains  truth  of  alignment  and  prevents  all 
yielding  or  vibration,  or  distortion  of  either  large  or  small 
parts,  and  to  the  severe  mechanical  correctness  of  all  move- 
ments, and  the  employment  of  the  very  best  materials,  we 
attain  in  all  the  working  parts,  practically,  entire  truth  of 
form,  true  plane,  and  true  cylindrical  surfaces,  and  we  make 
these,  wherever  it  is  desirable,  of  an  indestructible  character ; 
everywhere  when  wear  or  thrust  has  to  be  resisted,  we  provide 
large  and  well-fitted  surfaces. 


Porter-Allen  Engines 

All  excellences  of  mechanical  construction  will  be  found 
in  these  engines. 

We  do  not  compete  with  engines  in  which  anything 
whatever  is  sacrificed  to  cheapness  of  construction.  Our  con- 
fidence that  the  class  of  work  done  by  us  is  worth  doing  well 
and  will  be  appreciated,  has  been  amply  verified,  and  we  pro- 
pose to  maintain  a  uniformity  of  excellence  which  we  have 
been  at  the  utmost  pains  and  large  expense  to  insure. 

The  valve  gear  is  designed  to  give  the  best  possible  dis- 
tribution of  steam,  and  the  valves  are  small ;  have  short 
movements,  and  are  operated  without  loss  of  efficiency.  They 
are  four  in  number,  one  for  admission  and  one  for  release  at 
each  end  of  the  cylinder. 

These  valves  stand  in  the  vertical  position,  the  admission 
on  one  side  of  the  cylinder,  and  the  exhaust  on  the  other ;  the 
latter  are  so  placed  as  to  completely  drain  the  cylinder. 

These  valves  are  perfectly  balanced,  and  produce  practi- 
cally no  wear  on  the  seats.  Each  valve  opens  simultaneously 
four  passages,  two  on  each  face  for  the  admission  or  release  of 
the  steam. 


Porter- Allen  Engines 

Their  draft  is  central,  which  causes  both  the  valves  and 
their  seats  to  maintain  truly  plane  surfaces. 

The  exhaust  valves  are  in  contact  with  only  a  small 
portion  of  the  cylinder;  the  exhaust,  therefore,  abstracts 
externally  but  little  heat  from  the  cylinder,  and  none  from 
the  entering  steam. 

The  governor  is  of  the  well-known  Porter  type,  and 
stands  unexcelled  as  adapted  to  stationary  engines  requiring 
close  regulation.  The  active  parts  are  very  light,  the  power 
being  derived  from  a  high  rotative  speed,  causing  a  sensitive- 
ness in  its  movements  that  will  arrest  fluctuations  and 
produce  uniformity  in  the  running  of  the  engine. 

The  speed  of  this  governor  being  constant  makes  it  equally 
efficient  upon  an  engine  running  at  either  a  high  or  low  num- 
ber of  revolutions.  We  manufacture  and  sell  these  governors 
separate  from  our  engines. 

The  main  bed-plate  is  a  single  heavy  casting,  and  forms 
the  main  stay  and  backbone  of  the  engine.  It  has  a  very 
broad  base,  resting  with  large  surface  contact  on  the 
masonry,  continuously  from  one  end  to  the  other. 


Porter- Allen  Engines 

It  carries  trie  cross-head  guides,  and  all  the  brackets 
forming  part  of  and  carrying  the  main  valve-gear,  including 
the  governor,  thus  rigidly  securing  all  the  vital  parts  into 
one  main  body. 

At  one  end  of  this  bed-plate  is  provided  a  circular  hood 
of  substantial  character,  to  which  the  cylinder  is  attached; 
the  other  end  of  this  casting  contains  the  main  bearing  which 
is  fitted  with  heavy  quarter  boxes  and  binding  cap,  the  whole 
being  lined  with  our  best  Babbitt's  metal,  hammered  in  place, 
bored  and  scraped  to  a  perfect  fit  on  the  shaft. 

The  adjustment  of  the  quarter  boxes  in  the  main  bearing 
is  made  from  the  top  by  means  of  bolts  holding  wedge  slabs 
of  equal  length  to  the  journal,  thereby  insuring  a  most 
substantial  support  to  the  shaft. 

The  crosshead  has  large  bearing  surfaces  and  is  fitted 
with  a  forged  steel  pin  placed  in  the  middle  of  its  length. 
Being  incapable  of  deflection,  it  is  equally  in  contact  with  the 
guides  at  every  point. 

The  connecting  rod  has  a  solid  crank  end  and  strapped 
crosshead  end,  both  ends  having  boxes,  lined  with  our  best

Porter- Allen  Engines 

Babbitt's  metal,  soldered  or  fused  in  place,  bored  in  their 
respective  journals,  and  adjustable  to  maintain  a  constant 
length  of  the  rod. 

The  crank  is  of  disc  form,  cast  in  a  single  piece,  with 
turned  and  polished  rim,  the  turning  being  done  after  it  is 
applied  to  the  shaft,  and  is  suitably  counterbalanced.  The 
overhang  of  the  crank  is  reduced  to  the  least  amount 
consistent  with  proper  strength. 

The  crank  pin  is  made  of  special  steel.  The  hole  for 
the  crank  pin  in  the  disc  is  bored  after  the  disc  is  fitted  to 
the  shaft,  by  means  of  special  machinery,  insuring  an 
absolutely  true  alignment  with  the  shaft. 

These  engines  are  adapted  to  all  classes  of  service,  being 
used  extensively  upon  Electric  Street  Railways,  Electric 
Light  Stations,  Rolling  Mills,  Paper  Mills,  Silk  Mills,  and 
other  miscellaneous  industries. 

Opposite  page  10  is  illustrated  a  tandem  compound  con- 
densing Porter-Allen  Engine,  having  high  pressure  cylinder 
40  inches  diameter,  low  pressure  cylinder  75  inches  diameter, 
both  66  inches  stroke  of  piston.

Porter- Allen  Engines 

The  low  pressure  cylinder  is  supported  upon  an 
independent  base  plate,  and  is  attached  by  means  of  heavy 
tie  rods  to  the  hood  of  the  main  bed.  The  high  pressure 
cylinder  is  bolted  to  the  hood  in  the  usual  manner. 

The  fly-wheel  of  this  engine  is  25  feet  in  diameter  and 
weighs  180,000  pounds. 

The  engine  is  especially  designed  for  rolling  mill  service, 
and  couples  direct  to  the  roll  train. 

The  design  contemplates  a  speed  of  90  revolutions  per 
minute,  and  a  steam  pressure  of  150  pounds  per  square  inch 
at  the  throttle  valve. 

Our  standard  type  of  horizontal  crank  and  fly-wheel  Air 
Pump  and  Jet  Condenser  is  used  in  connection  with  this  engine. 

We  can  refer  to  many  examples  of  these  large  engines 
in  the  Steel  Works  throughout  our  Country. 

Opposite  we  illustrate  our  Compound  Porter-Allen  En- 
gine, adapted  to  driving  electric  generators  direct  connected 
to  main  shaft,  v/hich  practice  is  now  extensively  followed 
in  Street  Railway  and  other  service.

Porter- Allen  Engines 

This  class  of  work  is  similar  to  rolling  mill  require- 
ments, in  that  the  engine  is  subjected  to  sudden  and  extreme 
changes  of  load,  and  our  type  is  peculiarly  fitted  to  withstand 
this  successfully  owing  to  its  massive  construction,  and  the 
sensitive  governor  employed,  which  promptly  arrests  any 
fluctuations  in  speed  due  to  such  changes. 

At  the  same  time  we  give  the  most  refined  economy, 
by  reason  of  our  excellent  system  of  steam  distribution  and 
method  of  controlling  the  same,  which  is  described  in  the 
foregoing  pages. 

The  Delaware  Avenue  Station  of  the  Electric  Traction 
Company  of  Philadelphia,  of  which  the  cut  herewith  is  a 
reproduction,  is  fitted  up  exclusively  with  Porter-Allen 
Imgines,  Compound  Condensing,  there  being  five  in  all. 

Four  of  these  engines  have  a  nominal  capacity  of  1050 
horse  power  each,  with  high  pressure  cylinder  24  inches 
diameter,  low  pressure  cylinder  46  inches  diameter,  by  42 
inches  stroke  of  piston.  The  fifth  engine  is  of  350  horse 
power,  with  high  pressure  cylinder  14^  inches  diameter, 
low  pressure  cylinder  26  inches  diameter,  by  24  inches 
stroke  of  piston. 


Porter- Allen  Engines 

The  large  units  are  designed  for  a  speed  of  120  revolu- 
tions per  minute  and  the  small  engine  200  revolutions.  The 
generators  are  of  800  and  250  K.  W.  capacity  respectively. 

The  main  shaft  of  the  large  engines  is  carried  in  three 
bearings,  the  generator  being  located  between  the  middle 
and  outer  bearings,  which  latter  can  be  readily  taken  away 
to  facilitate  removal  of  armature  if  necessary. 

In  the  case  of  the  small  engine,  the  shaft  runs  in  two 
bearings,  the  generator  being  attached  to  the  end  of  the 
shaft,  which  is  prolonged  through  the  outer  bearing  for  that 
purpose. 

These  engines  are  liberally  proportioned  in  all  their 
parts,  the  fly-wheels  being  very  heavy,  while  the  main 
shafts,  bearings,  crank  pins,  etc.,  are  unusually  large.  In 
addition  to  this  the  whole  design  is  exceedingly  compact 
and  occupies  a  minimum  space. 

This  plant  is  only  one  of  many  examples  we  can  refer  to, 
having  supplied  our  engines  of  the  Porter-Allen  type,  both 
high  pressure  and  compound,  direct  connected  and  belted, 
of  various  sizes,  to  some  of  the  largest  street  railway  and 
power  stations. 

U 


Porter- Allen  Engines 

Our  Horizontal  Triple  Expansion  Porter-Allen  Engine  is 
shown  opposite  page  14.  The  high  and  low  pressure  cylin- 
ders are  placed  on  one  side  tandem,  while  the  intermediate 
cylinder  acts  upon  a  crank  at  the  other  end  of  the  main  shaft, 
which  is  set  at  right  angles  to  the  high  pressure  crank. 

The  valves  in  both  the  intermediate  and  low  pressure 
cylinders  of  this  engine  are  arranged  and  driven  the  same  as 
those  in  the  high  pressure  cylinder,  excepting  they  are  not 
controlled  by  the  governor. 

All  of  the  general  features  of  excellence  before  de- 
scribed, are  introduced  in  these  engines,  and  special  care 
is  taken  to  make  them  readily  accessible  for  inspection  or 
repairs. 

The  arrangement  of  cylinders  is  subject  to  modification 
to  suit  special  requirements. 

Our  Quadruple  Engines  are  built  in  the  same  general 
style  as  the  last  named  engine,  acting  on  four  cranks,  each 
cylinder  single,  or  on  two  cranks  with  two  pairs  of  cylinders, 
set  tandem. 


VERTICAL  ENGINES 

WE  Here  illustrate  a  Vertical  Triple  Expansion  Engine, 
which   can  be  built  to  suit  any  purpose  desired. 
As  arranged  in  the  pictures,  it  is  adapted  to  drive, 
direct  connected  to  the  main  shaft,  two  electric  generators, 
one  on  each  end. 

This  type  of  engine  not  only  possesses  the  important 
features  of  high  economy  and  close  regulation,  but  in  com- 
pactness and  accessibility  is,  we  believe,  in  the  lead  of  all 
other  engines  of  similar  class  offered  at  this  time. 

A  special  patented  valve  gear  is  adopted  on  these  engines 
by  which  the  admission  of  steam  can  be  regulated  from  zero 
to  75  per  cent. 

The  main  bed  is  a  single  casting,  without  external  ribs 
but  heavily  ribbed  internally,  provided  with  ample  bearing 

16

surface  for  resting  on  the  foundation,  and  of  sufficient  rigid- 
ity to  insure  perfect  alignment  of  all  bearings. 

The  bearings,  four  in  number,  are  solidly  bedded  in 
the  main  bed  plate,  covered  and  held  by  strong  cast  iron 
caps.  They  are  so  designed  that  the  bottom  box  can 
be  removed  and  replaced  without  lifting  the  shaft  more 
than  the  usual  clearance  between  the  armature  and  the 
field  magnets  in  the  dynamos.  The  boxes  are  lined  with 
our  best  Babbitt's  metal. 

The  shaft  is  of  forged  steel,  the  cranks  on  the  same  being 
formed  by  cast  steel  discs,  shrunk  on  and  keyed. 

The  two  outer  discs,  connecting  with  the  low  and  inter- 
mediate cylinders  respectively,  are  united  by  means  of  heavy 
crank  pins,  forced  into  the  discs  and  riveted  on  the  back  of 
same.  The  middle  crank  pin,  connecting  with  the  high 
pressure  cylinder,  is  inserted  and  keyed  in  tapered  holes  and 
secured  by  nuts  on  the  back  of  the  discs. 

The  front  columns  are  of  hammered  iron,  turned  and 
polished.  To  these  columns  are  attached  brackets  for  the 
valve  gear,  as  well  as  the  front  platform.  The  rear  columns 
are  of  cast  iron,  of  box  section. 

17 


Vertical  Engines 

The  base  oi  the  rear  columns  is  of  liberal  size  where 
fastened  to  the  bed,  and  the  top  extends  forward  and  rests  on 
the  front  wrought  iron  columns,  thus  forming  an  entabla- 
ture, to  the  top  of  which  the  cylinders  are  firmly  bolted. 

The  back  columns  carry  the  guides,  which  are  of  ribbed 
plate  pattern.  These  guide  plates  also  serve  as  ties  between 
the  columns,  making  a  most  rigid  connection  between  the 
same  in  a  direction  parallel  to  the  shaft. 

The  cylinders  are  placed,  as  already  implied,  with  the 
high  pressure  cylinder  in  the  center,  and  intermediate  and 
low  pressure  on  opposite  sides  of  the  same.  These  cylinders 
are  firmly  bolted  together  at  the  lower  end,  one  flange 
being  recessed,  or  checked  into  the  other.  The  upper  ends 
are  united  by  means  of  loose  fitting  bolts,  thus  enabling 
the  cylinders  to  expand  longitudinally  at  a  rate  corres- 
ponding to  the  temperature  oi  each  one,  without  disturbing 
the  alignment. 

Each  cylinder  is  provided  with  four  valves,  two  for 
admission  and  two  for  exhaust.  These  valves  are  covered  by 
inflexible  covering  plates,  entirely  relieving  the  valves  of  any 
pressure  and  making  them  as  nearly  balanced  as  is  practicable.

COUPLED    DIRECT   TO   TWO   400   K.  W.   ELECTRIC   GENERATORS 


Vertical  Engines 

The  motion  for  the  steam  valves  of  each  cylinder  is  taken 
from,  the  connecting  rod,  the  valve  gear  being  of  our  pat- 
ented radial  type.  It  consists  of  a  system  of  rods  and  levers, 
joined  by  means  of  case  hardened  and  ground  steel  pins, 
running  in  case  hardened  and  ground  steel  ferrules,  thereby 
reducing  the  friction  to  a  minimum. 

The  admission  valve  gear  for  the  high  pressure  cylinder 
is  automatically  controlled  by  a  Porter  governor,  driven  by 
gearing  from  the  main  shaft.  The  admission  valves  for  the 
intermediate  and  low  pressure  cylinders,  as  well  as  the  exhaust 
valves  for  all  the  cylinders,  are  adjustable  by  hand  to  any 
desirable  degree. 

In  the  year  1894  we  installed  in  the  Harrison  Street 
Station  of  the  Chicago  Edison  Company,  eight  of  these 
engines,  aggregating  a  nominal  horse  power  of  7200.  Care- 
ful tests  made  by  disinterested  engineers  showed  an  actual 
water  consumption  of  13.35  pounds  per  horse  power  per 
hour,  and  a  regulation  within  i^J  per  cent,  of  the  normal 
speed. 

We  also  build  vertical  engines  simple  and  compound 
of  this  type. 


O 


BLOWING  ENGINES 

UR  Standard  Vertical  Blowing  Engine  is  illustrated  on 
opposite  page. 


We  build  these  engines  for  Blast  Furnace  and  Bessemer 
Steel  Works'  requirements,  either  simple  or  compound. 

The  engine  here  shown  has  a  single  steam  cylinder,  fitted 
with  four  independent  balanced  valves  of  the  Porter- Allen  type, 
two  controlling  the  admission  and  two  the  release  of  the  steam. 

The  admission  valves  may  be  controlled  either  by  hand 
or  by  our  Porter  Governor  automatically.  In  the  latter  case 
the  governor  is  so  arranged  as  to  give  a  wide  range  of  speeds 
and  thereby  meet  any  conditions  that  might  arise  requiring 
a  greater  or  less  number  of  revolutions.  This  governing  gear 
is  readily  adjusted  while  the  engine  is  running. 


SOUTHWARK    BLOWING   KNGINE 


Blowing  Engines 

As  will  be  seen,  the  steam  cylinder  is  placed  between 
the  housings,  which  are  strongly  ribbed  castings,  extending 
from  the  bed-plate,  upon  which  they  rest,  up  to  the  lower 
head  of  the  air  cylinder,  and  containing  the  cross-head 
guides. 

The  bed-plate  is  a  single  heavy  casting  in  which  the  main 
bearings  are  formed.  The  main  shaft  which  is  carried  in 
these  bearings,  has  a  fly-wheel  fitted  on  each  end.  These 
wheels  also  act  as  cranks  which  are  coupled  by  means  of 
connecting  rods  to  the  cross-head. 

The  piston-rods,  both  air  and  steam,  are  attached  to  the 
cross-head  by  means  of  a  swivel  block,  which  permits  the 
cross-head  to  adjust  itself  to  the  varying  lengths  of  the 
connecting  rods. 

The  bottom  air-head  rests  upon  and  is  attached  to  the 
housings  as  before  explained.  The  air  cylinder  is  placed 
upon  this  head,  and  in  turn  carries  the  top  head. 

The  valves  in  the  top  and  bottom  air-heads  are  of  our 
patented  gridiron  type.  They  give  an  unrestricted  port  open- 
ing of  ample  area,  which  permits  the  air  to  enter  and  leave 


21 


Blowing  Engines 

the  cylinder  with  the  least  possible  friction,  thus  insuring  a 
maximum  discharge  per  piston  displacement. 

These  valves  have  short  stroke  and  move  when  in  equi- 
librium, thereby  reducing  wear  to  a  minimum.  Those  for  the 
inlet  of  air  are  operated  positively  by  means  of  a  cam,  actuated 
through  the  medium  of  rods  and  levers  by  an  eccentric  on 
the  main  shaft,  while  those  for  the  outlet  of  air  receive  their 
movement  from  a  piston  on  the  stem  of  the  valve,  upon  which 
the  pressure  in  the  air  cylinder,  and  in  the  receiver,  acts 
alternately  to  open  and  close,  and  are  entirely  automatic 
at  any  pressure. 

By  this  system  the  engine  can  be  run  at  any  speed 
desired,  and  further  a  full  movement  of  all  the  valves  is 
assured. 

The  engine  opposite  is  shown  in  partly  finished  state, 
and  embodies  all  the  features  heretofore  mentioned,  but  the 
steam  end  is  made  compound,  both  cylinders  acting  upon  a 
single  crosshead.  One  of  these  engines,  32  and  60  inches 
diameter  of  steam  cylinders,  with  air  cylinder  80  inches  diam- 
eter by  48  inches  stroke,  is  running  at  the  Joliet  Works  of  the 
Illinois  Steel  Company.

SOUTHWARK    BLOWING    ENGINE,    COMPOUND   CONDENSING 


Blowing  Engines 

The  cut  in  outline,  opposite  page  24,  represents  our  Dis- 
connected Compound  Vertical  Blowing  Engine.  As  shown 
it  consists  of  a  high  pressure  engine,  having  steam  cylinder 
40  inches  diameter,  air  cylinder  72  inches  diameter,  and  a 
stroke  of  60  inches ;  a  low  pressure  engine,  having  steam 
cylinder  75  inches  diameter,  air  cylinder  72  inches  diameter, 
and  60  inches  stroke.  These  engines  are  designed  to  run 
50  revolutions  per  minute  in  regular  service,  but  are  built 
strong  enough  for  a  speed  of  60  revolutions  per  minute 
should  the  exigencies  of  the  service  require  it. 

The  unique   feature  of    these  engines  is,  that   the  low 

pressure  side  is   entirely   separate  and   independent   of  the 

high   pressure  side,  the   only   connection   between    the  two 
being  the  receiver  for  reheating  the  steam. 

A  Porter  governor  and  link  motion  controls,  automatic- 
ally, the  supply  of  steam  to  the  high  pressure  cylinder,  and  it 
has  been  found  in  practice  that  the  low  pressure  engine 
requires  no  governing  device,  nor  live  steam  connection,  as 
the  supply  from  the  high  pressure  cylinder  is  adequate  under 
all  conditions  of  work  to  cause  the  engines  to  run  at  precisely 
equal  speed. 


Blowing  Engines 

A  system  of  gate  valves  is  provided  so  that  either 
engine  of  the  pair  can  be  run  separately,  condensing  or  non- 
coiidensing,  as  the  occasion  may  demand,  which  affords 
every  possible  convenience  in  the  event  of  repair. 

The  heads  of  the  air  cylinders  are  equipped  with  our 
patented  gridiron  valves  as  already  described. 

The  facility  with  which  these  engines  can  be  run 
independent  of  each  other  with  or  without  the  condenser, 
by  the  simple  manipulation  of  the  gate  valves  before  men- 
tioned, coupled  with  the  economy  due  to  compounding, 
when  run  as  a  pair,  has  made  this  dis-connected  type  very 
popular ;  one  Steel  Works  alone  having  purchased  six  pairs 
of  these  engines  in  the  last  two  years. 

A  Southwark  Horizontal  Independent  Crank  and  Fly- 
wheel Air  Pump  and  Jet  Condenser  is  used  in  connection 
with  this  engine. 

Opposite  page  26  is  illustrated  a  battery  of  Vertical 
Blowing  Engines  consisting  of  ten  engines,  each  having  a 
steam  cylinder  42  inches  diameter,  air  cylinder  84  inches 
diameter,  both  60  inches  stroke  of  piston. 


Blowing  Engines 

They  are  located  in  the  engine  room  of  Furnaces  5,  6,  7 
and  8  of  the  South  Chicago  Works  of  the  Illinois  Steel 
Company,  where  they  have  been  in  operation  for  the  past 
six  years. 

These  engines  were  all  built  by  our  Company. 

The  two  pictures  following  page  28  are  from  photo- 
graphs taken  in  the  Works  of  the  Cleveland  Rolling  Mill 
Co.,  Cleveland,  Ohio,  and  represent  our  Improved  Horizontal 
Automatic  Twin  Bessemer  Blowing  Engine,  with  steam 
cylinders  working  on  cranks  set  at  right  angles  on  the 
shaft,  and  a  fly-wheel  applied  in  the  middle  of  the  shaft; 
each  steam  cylinder  having  its  own  air  cylinder  placed 
in  a  straight  line  behind  it. 

The  steam  cylinders  in  this  case  are  44  inches  diameter 
and  the  air  cylinders  60  inches  diameter,  by  60  inches 
stroke  of  piston. 

The  steam  cylinders  are  of  the  Porter -Allen  type, 
having  four  balanced  valves,  those  for  admission  in  each 
cylinder  being  controlled  automatically  by  a  Porter  Governor 
and  link  motion. 


Blowing  Rngines 

The  air  heads  are  fitted  with  our  patented  oscillating 
gridiron  valves.  Those  for  inlet  of  air  are  operated  posi- 
tively by  a  cam  motion,  while  the  outlet  valves  are  operated 
by  special  cylinders  and  valve  motion  for  same,  which  cause 
them  to  open  and  close  automatically  according  to  the  air 
pressure  it  is  desired  to  blow  into  the  converters. 

An  important  feature  of  these  valves  is  the  fact  that 
when  they  are  in  motion  they  do  not  touch  their  seats  thus 
preventing  all  wear.  One  set  has  been  in  constant  use  at 
the  works  of  the  Cambria  Iron  Co.,  Johnstown,  Pa.,  for  a 
period  of  six  years,  and  are  as  good  as  when  first  applied. 

The  bed  plates  of  these  engines  are  of  massive  pro- 
portions, extending  from  and  including  the  main  bearing 
to  the  steam  cylinder. 

Heavy  tie  rods  connect  the  air  cylinders  to  the  beds,  in 
addition  to  which  a  further  support  is  given  these  cylinders 
by  substantial  sole  plates,  extending  under  and  attaching  to 
the  steam  cylinder. 

We  also  build  these  engines  with  compound  steam 
cylinders,  adapted  either  to  Blast  Furnace  or  Bessemer  work.

COMPRESSORS  FOR  NATURAL  GAS 

NK  of  the  uses  to  which  our  improved  gridiron  valve 
has  been  successfully  applied,  is  the  pumping  of  nat- 
ural gas. 


Its  great  durability  and  positive  action  makes  it  pecu- 
liarly fitted  for  this  class  of  work.  We  illustrate  opposite 
page  30  one  of  these  Compressors,  having  compound  steam 
and  gas  cylinders,  arranged  with  a  system  of  valves  so  as 
to  run  both  gas  cylinders  high  pressure  as  well  as  com- 
pound, or  either  side  as  a  single  engine. 

To  show  the  efficiency  of  this  air  gear  we  would  state 
that  these  engines  run  night  and  day  at  60  revolutions  per 
minute,  and  work  equally  well  from  3  pounds  to  100  pounds 
gas  pressure. 


29 


Compressors  for  Natural  Gas 

The  gas  cylinders  are  effectively  water  jacketed,  and  when 
running  compound,  in  passing  from  the  low  pressure  to  the 
high  pressure  cylinder,  the  temperature  of  the  gas  is  reduced 
by  the  use  of  an  efficient  cooler. 

The  general  design  of  these  compressors  is  the  same  as 
our  horizontal  blowing  engines,  and  we  shall  be  pleased  to 
furnish  prospective  purchasers  with  full  information  and 
prices.

REVERSING  ENGINES 

UR  type  of  Reversing  Engine  for  Blooming  Mills, 
shown  in  outline  drawing,  has  been  used  in  the  Steel 
Works  for  a  long  time. 


We  can  refer  to  examples  at  the  Works  of  the  Cam- 
bria Iron  Co.,  Johnstown,  Pa. ;  Carnegie  Steel  Co.,  Pittsburgh, 
Pa. ;  Otis  Steel  Co.,  Cleveland,  Ohio;  Pennsylvania  Steel  Co., 
Steel  ton,  Pa.  ;  Potts  town  Iron  Co.,  Potts  town,  Pa.  ;  Spring- 
field Iron  Co.,  Springfield,  111.,  and  Wheeling  Steel  Works, 
Wheeling,  W.  Va.  All  of  these  engines  are  of  large  size, 
ranging  from  28"  x  48"  to  44"  x  60"  cylinders. 

The  design  is  massive  and  intended  to  withstand  the 
heaviest  shocks  common  to  this  service.  The  steam  cylinders 
are  rigidly  attached  to  the  beds,  and  are  fitted  with  a  single 
double-ported  balanced  slide  valve,  driven  by  eccentrics  on 
the  main  shaft. 


Reversing  Engines 

The  reversing  links  are  operated  by  an  hydraulic  engine 
placed  between  the  bed-plates,  and  controlled  from  the  work- 
ing platform,  which  is  placed  in  a  convenient  location. 

The  throttle  valves  are  also  operated  from  this  platform. 

The  bed-plates  are  an  adaptation  of  the  design  used 
in  our  Porter-Allen  Engine,  which  we  believe  is  the  best 
form  yet  devised  for  engines  subjected  to  severe  and  contin- 
uous strains. 

The  gearing  is  of  steel,  the  pinion  being  cast  solid,  while 
the  rim  of  the  spur  wheel  is  fitted  to  a  cast-iron  spider  to 
facilitate  renewal. 


CENTRIFUGAL  PUMPS 

WE  make  a   specialty  of  Centrifugal  Pumps  for  Dry 
Dock,    Drainage,    Irrigation,    Sewerage    and   other 
purposes,  where  a  large  quantity  of  water  is  required 
to  be  quickly  handled. 

We  claim  the  distinction  of  being  the  first  concern  in  the 
United  States  to  build  this  class  of  pump  in  the  large  sizes, 
and  are  pleased  to  refer  to  the  following  Government  Dry 
Docks  which  we  have  equipped  with  our  machinery: 

UNITED  STATES  NAVY  YARD,  Mare  Island,  Cal. 

"  "  "  Portsmouth,  Va. 

League  Island,  Pa. 

Brooklyn,  N.  Y. 

Boston,  Mass. 
UNITED  STATES  NAVAL  STATION,  Port  Royal,  S.  C.

In  addition  we  have  equipped  the  following  private  docks : 

NEWPORT  NEWS  SHIP  BUILDING  &  DRY  DOCK  COMPANY, 
Newport  News,  Va. 

CLEVELAND  DRY  DOCK  COMPANY, 
Cleveland,  Ohio. 

CHICAGO  SHIP  BUILDING  COMPANY, 
Chicago,  111. 

Where  the  lift  is  not  excessive,  this  type  of  Pump  is 
admirably  adapted  for  pumping  sewage  and  drainage  water, 
and  we  have  built  a  large  number  for  that  purpose.  Promi- 
nent among  the  places  where  our  plants  can  be  seen  in 
operation  in  this  service  are  City  of  Philadelphia,  Pa.  ; 
City  of  Chicago,  111.;  City  of  Stamford,  Conn. 

Besides  which,  we  have  built  a  great  many  of  various 
sizes  for  private  parties. 

We  illustrate  opposite  two  of  these  pumps  having  dis- 
charge openings  42  inches  diameter,  each  pump  being  driven 
direct  by  a  vertical  engine,  28  inches  diameter  01  cylinder 
and  24  inches  stroke  of  piston. 

A  portion  of  the  piping  and  gate  valves  is  also  shown, 
applicable  to  dry  dock  service. 

34 


Centrifugal  Pumps 

This  size  of  pump  has  a  nominal  capacity  ot  40,000 
gallons  of  water  per  minute,  but  has  shown  on  repeated 
tests  an  actual  discharge  of  over  50,000  gallons  per  minute. 

We  quote  from  the  official  report  of  the  test  made  01 
the  first  pair  of  these  pumps  built  by  us  for  the  United  States 
Government.  These  pumps  were  installed  at  the  Dry  Dock, 
U.  S.  Navy  Yard,  Mare  Island,  Cal.,  in  1885  : 

Extracts  from  the  Report. 

"Contract  requirement,  a  mean  discharge  of  80,000  gal- 
lons per  minute  from  both  pumps." 

"Actual  mean  discharge  from  both  pumps  112,922 
gallons  per  minute." 

"Greatest  discharge,  137,797  gallons  per  minute." 

In  transmitting  a  copy  of  the  report  to  us,  the  Bureau  ol 
Yards  and  Docks  wrote  as  follows  : 

"  The  Bureau  in  forwarding  a  copy  of  the  report,  desire 
also  to  congratulate  you  upon  the  successful  and  unprece- 
dented performance  of  the  pumps." 


35 


Centrifugal  Pumps 

The  official  tests  made  of  our  machinery  at  the  other 
Government  Dry  Docks,  subsequent  to  the  above,  have  shown 
results  equally  satisfactory. 

A  convenient  and  compact  arrangement  of  pump  and 
engine  is  shown  opposite. 

This  design  contemplates  a  single  bed- pi  ate,  common  to 
pump  and  engine,  the  fly-wheel  acting  as  a  coupling  between 
the  crank  and  runner-shafts. 

We  have  suppled  them  in  this  form  for  drainage  service 
at  the  various  dry-docks,  and  for  other  purposes  where  a  self- 
contained  pump  was  preferred. 

Where  an  electrical  current  is  available,  an  economical 
method  of  driving  Centrifugal  Pumps,  especially  of  the  smaller 
sizes,  is  by  means  of  a  motor  coupled  direct  to  the  runner-shaft, 
and  we  have  designed  and  built  them  in  this  manner,  combin- 
ing the  pump  and  motor  on  a  bed-plate  common  to  both,  as 
per  second  illustration  following. 

This  arrangement  is  particularly  applicable  where  the 
pump  is  located  at  a  distance  from  the  boiler  plant,  as  it  avoids 
the  running  of  long  steam  pipes,  and  the  consequent  condensa-

tion,  or  the  necessity  for  additional  boilers  with  increased 
attendance,  and  provision  for  handling  coal  and  ashes  at  the 
site  of  the  pump.  The  simple  running  of  the  wires  being  all 
that  is  required  in  the  case  of  the  electrically  driven  pump. 

Where  steam  is  used  to  drive  these  pumps,  it  has  been 
found  desirable  to  furnish  a  plain  high  pressure  engine,  if 
the  service  is  intermittent,  like  in  dry  docks,  as  the  saving 
in  first  cost  is  more  to  be  considered  than  a  refined  economy 
in  steam  consumption. 

This  condition  only  applies,  however,  to  cases  where  the 
machinery  is  operated  but  a  short  time  at  long  intervals. 

If  the  pumping  is  constant,  or  nearly  so,  we  recommend 
a  refined  economical  steam  engine  for  the  work,  and  have 
usually  supplied  compound  or  triple  expansion  engines. 

A  plant  for  constant  service  is  shown  opposite  page  38. 
It  consists  of  three  pumps,  having  discharge  openings  24 
inches  diameter,  each  direct  driven  by  a  Compound  Condens- 
ing Porter- Allen  Engine,  with  cylinders  12  inches  and  22 
inches  diameter  by  24  inches  stroke  of  piston. 

The  combined  capacity  of  these  pumps  is  72,000,000 
gallons  every  24  hours. 

37 


Centrifugal  Pumps 

This  plant  was  installed  by  our  Company  in  the  South 
Chicago  Works  of  the  Illinois  Steel  Company,  and  supplies 
water  for  their  Blast  Furnaces  and  other  purposes. 

It  has  been  in  operation  over  five  years,  and  careful  tests 
have  shown  a  high  degree  of  efficiency. 

We  can  also  refer  to  similar  plants  at  the  Works  of  the 
Cambria  Iron  Company,  Johnstown,  Pa.,  Pottstown  Iron  Com- 
pany, Pottstown,  Pa.,  and  the  Johnson  Company,  L/orain,  Ohio. 

Careful  attention  has  been  observed  by  us  in  designing 
these  pumps  to  maintain  uniform  water  ways  throughout. 
The  runner  is  of  the  double  enclosed  type,  the  suction  entering 
by  easy  turns  at  each  side,  thus  effectively  balancing  it  and 
avoiding  all  lateral  thrust  on  the  shaft. 

The  runner-shaft  is  liberally  proportioned  to  insure  perfect 
rigidity  in  working,  and  is  carried  in  bronze  bearings,  which 
are  lubricated  automatically  while  the  pump  is  in  operation,  by 
the  water  being  pumped. 

The  casing  is  constructed  so  as  to  provide  for  the  ready 
removal  of  the  runner,  without  disturbing  the  joints  in  the 
suction  or  discharge  pipes. 


Centrifugal  Pumps 

The  design  of  our  casing  also  permits  of  the  suction 
entering  and  the  discharge  leaving  the  pump  in  any  direction 
desired. 

It  is  very  essential  in  this  type  of  pump  to  pay  careful 
attention  to  the  interior  construction.  We  not  only  design 
all  parts  liberally,  which  makes  our  pumps  larger,  size  for 
size,  than  any  others  in  the  market,  but  also  machine  the 
runner  all  over,  thereby  completely  balancing  it,  and  thor- 
oughly clean  all  the  passages,  coating  the  same  with  iion-cor- 
rosive  paint. 

The  pumps  already  described  are  what  is  known  as  the 
horizontal  pattern,  the  shaft  being  in  a  horizontal  plane. 

We  also  make  Centrifugal  Pumps  of  the  submerged  type, 
having  the  shaft  in  a  vertical  position. 

An  illustration  of  one  of  these  pumps  is  given  opposite 
page  40. 

While  this  style  of  pump  is  not  so  accessible  for  examina- 
tion as  the  other  style,  yet  there  are  certain  situations  where 
they  can  be  used  to  greater  advantage. 

The  principal  points  in  its  favor  are  the  absence  of  all 

39 


Centrifugal  Pumps 

suction  pipes  and  the  fact  of  its  being  constantly  primed  ready 
for  operation. 

We  have  lately  completed  for  the  United  States  Govern- 
ment a  plant  consisting  of  three  submerged  pumps,  with 
discharge  openings  30  inches  diameter,  and  one  10  inches 
diameter. 

These  pumps  are  located  in  the  new  Soofoot  Lock  at 
St.  Marys  Falls,  Mich. 

We  build  our  Centrifugal  Pumps  in  sizes  from  8  inches 
to  42  inches  diameter,  and  are  prepared  to  undertake  the 
engineering  and  complete  installation  of  plants  for  all  classes 
of  service.

WATER  WORKS  PUMPING  ENGINES 

NE  of  the  important  branches  of  our  business,  is  the 
designing  and  building  of  High  Duty  Pumping 
Engines  for  Water  Works. 


Our  experience  in  this  field,  coupled  with  the  excellent 
facilities  we  possess  for  handling  heavy  work,  enables  us  to 
construct  these  engines  of  the  largest  sizes. 

The  illustration  opposite  page  42  is  of  a  Vertical  Com- 
pound Condensing  Crank  and  Fly-wheel  Pumping  Engine, 
having  a  capacity  of  15,000,000  gallons  every  24  hours. 

This  type  of  pump  is  very  convenient  and  accessible  for 
operating,  and  occupies  comparatively  small  floor  space. 


Water  IVorks  Pumping  Engines 

The  dimensions  are  as  follows  : 

High  Pressure  Steam  Cylinder,  44  inches  diameter. 
Low  Pressure  Steam  Cylinder,  88  inches  diameter. 
Two  Water  Plungers,  28  inches  diameter. 
All  42  inches  stroke. 

In  many  cases  it  is  necessary  to  design  a  pump  to  occupy 
a  limited  space,  a  condition  which  frequently  occurs  in  re- 
modeling or  enlarging  old  Water  Works. 

We  have  repeatedly  been  called  upon  to  meet  cases  ot 
this  kind,  and  the  second  plate  following  is  an  example  of  a 
special  pump  of  this  character,  two  of  which  we  have  built. 

This  cut  shows  a  High  Duty  Twin  Compound  Condens- 
ing Crank  and  Fly-wheel  Pumping  Engine,  in  which  the 
steam  cylinders  are  placed  vertically,  while  the  water  cylinders 
are  horizontal. 

The  design  of  this  pump  was  made  necessary  by  reason 
of  the  available  space  being  too  small  for  a  horizontal  engine, 
and  the  situation  not  permitting  of  a  pit  for  a  vertical  engine. 

As  will  be  seen  in  the  cut,  the  motion  of  the  steam  pistons 
is  transmitted  to  the  water  plungers  through  rocking  beams.

The  design  is  massive,  and  has  proven  to  be  a  very  efficient 
one.     Its  capacity  is  20,000,000  gallons  every  24  hours. 

The  increasing  demand  for  higher  duty  in  Water  Works 
Pumping  Engines  has  compelled  the  adoption  in  many  in- 
stances of  the  Triple  Expansion  type,  and  we  present  an 
outline  sectional  elevation  of  one  of  four  2O,ooo,ooo-gallon 
pumps  designed  and  built  by  us  on  these  lines. 

A  reference  to  the  cut  will  show  many  unique  features, 
prominent  among  which  is  the  absence  of  the  usual  masonry 
foundation  ;  in  its  place  is  a  plate  steel  substructure  which 
while  of  ample  stiffness,  affords  unusual  access  to  all  parts  of 
the  water  end. 

The  dimensions  of  the  Triple  Expansion  Pumping 
Engine  referred  to,  are  as  follows  : 

H.  P.  Cylinder,  37  inches  diameter. 

I .  P.  Cylinder,  62  inches  diameter. 

L.  P.  Cylinder,  96  inches  diameter. 

Water  Plungers  (three),  34^2  inches  diameter. 

All  54  inches  stroke.

Heater  Works  Pumping  Engines 

We  are  prepared  to  submit  designs  of  Pumping  Engines 
for  Water  Works  to  meet  any  requirement,  and  shall  be 
pleased  to  consult  with  Cities  or  private  parties,  when  con- 
templating the  purchase  of  such  machinery.

GENERAL 

IN    addition    to    the   specialties   already  treated    upon,  we 
would   explain    that  we   have   built   Hydraulic   Bloom 
Shears,  Intensifiers,  Ingot  Extractors,  Charging  Machines, 
Hydraulic   Pressure    Pumps,    Hydraulic    Presses    and    other 
miscellaneous  work  of  heavy  and  special  character. 

We  solicit  inquiries  in  this  line ;  also  for  castings  of  any 
size  and  weight  up  to  100,000  pounds. 

We  illustrate,  as  an  example  of  heavy  boiler  work,  a 
battery  of  four  Marine  Boilers,  each  u  feet  9  inches  diameter 
by  10  feet  10  inches  long,  built  by  us  for  the  City  of 
Philadelphia.  We  have  furnished  twenty-three  of  these  large 
boilers  to  this  city  alone,  besides  having  supplied  them 
equally  large  with  our  Dry  Dock  Pumping  Plants.

We  also  illustrate  as  an  example  of  heavy  machine  work, 
a  Disappearing  Gun  Carriage,  two  of  which  we  built  for 
the  Ordnance  Office  of  the  U.  S.  Army.  These  carriages,  the 
first  of  their  kind,  were  ordered  by  the  Government  as  an 
experiment.  When  completed  by  us  and  delivered  to  the 
U.  S.  Proving  Ground,  Sandy  Hook,  N.  J.,  they  were 
subjected  to  the  most  severe  tests  and  withstood  the  same 
successfully.  The  material  of  these  carriages,  was  the  best 
open  hearth  steel  throughout,  and  the  specifications  called 
for  a  most  refined  and  accurate  finish.  Every  detail  was 
examined  critically  by  the  Government  Inspectors,  and 
passed  upon  as  a  perfect  piece  of  work. 

We  can  point  to  many  other  examples  of  our  facilities 
for  handling  varied  work  of  large  character,  and  of  a  nature 
requiring  accurate  workmanship  and  best  materials.
